Typing this from Bangalore after having driven some 500km. The Max FE returned so far is 9 Km/L with speed consistently hitting some 20km/h higher than what I used to do with my Scorp.Even at 150km/h, the vehicle was rock solid and had some significant juice left. It is fun to drive once you go past, say, 90kmph on 4/6 Lane roads.
I believe thats because yours is Endy Everest 3.0L Edition. There's a definite difference between 2L and 3L engines. The 3L is a big game up. Sadly these are being a rarity in India whereas in USA and other developed countries even 4.2L engines are commonly available.
